Visualization Software

SAGA - System for Automated Geoscientific Analyses - is a Geographic Information System (GIS) software with immense capabilities for geodata processing and analysis. SAGA is programmed in the object oriented C++ language and supports the implementation of new functions with a very effective Application Programming Interface (API). Functions are organised as modules in framework independent Module Libraries and can be accessed via SAGA’s Graphical User Interface (GUI) or various scripting environments (shell scripts, Python, R, ...).
Have a look at the SAGA web site for more details.

Viking is a free/open source program to manage GPS data. You can import, plot and create tracks, routes and waypoints, show OSM, Terraserver, Bing Aerial and other maps, geotag images, see real-time GPS position, get geocaches, control items, etc. It is written in C & the GTK+2 toolkit.

A command line tool for generating timing diagrams from ASCII input files. The input files use a structured language to represent signal state transitions and interdependencies. Raster image output support is provided by ImageMagick.

A high performance visualization tool for stars and particles able to run on Beowulfs. Rendering step is implemented separately and optimized for SSE, compatible with OpenGL. Navigation mechanism with quaternions. Ten color maps, sobel contour detect

Software tools facilitating the task of surveying architecture (real-time control, parametric modelling, use of digital photographs, processing of point clouds...).
Until now, those tools were mainly used to document cultural heritage sites/buildings

VR Juggler is a virtual platform for virtual reality application development created at the Virtual Reality Applications Center at Iowa State University. Applications developed in VR Juggler can transparently move between a wide range of VR systems.

Conic Planet is a CGI application which renders a photo-realistic real-time image of the Earth and other planets. It has support for Azimuthal, Mercator, Mollweide, Orthographic, and Rectangular projections. It also shows the current cloud covering.

Ledctl is a program written in C that uses the Parallel Port Interface(PPI) of the FreeBSD kernel to drive LEDs connected to the parallel port of a computer. It can be used within scripts to visually notify users for new mail, high processor load, etc.
